AIR-PURIFICATION APPARATUS.

Application led September 19, 1919. Serial No. 824,910.

i o all whom t may concern:

Be it known that I, HERMAN A. LOOSE, a citizenof the United States, residing at Cleveland in the county of Cuyahoga and State of hio, have invented a certain new and useful Improvement in Air-Purification Apparatus, of which the following is a full, clear, and exact description, reference being had to the accompanylng drawings.

This invention relates to ozone inhalation and air purification apparatus and more particularly-to that class of apparatus wherein pure ozone is produced and mixed with vaporized oil.

The Objects of the present invention are to provide an apparatus suitable for individual treatment or for collective treatment; to provide novel heating and drying means for the air from which the Ozone is roduced; to provide a novel form of combmed discharge gap, liquid container, and air heater; to provide an apparatus simple in construction and inexpensive to manufacture; to provide an apparatus, the parts of which shall be readily accessible for cleaning; while further objects and advantages will appear as the description proceeds.

In the drawings, wherein I have shown certain illustrative embodiments of my said invention, Fig. l is a section of the line 1-1 of Fig. 2; Fig. 2 is a top plan view of the instrument; Fig.' 3 is a per ctive view of the U-tube used for indivi ual treatment; and Fig. 4 is a diagram showing the electrical circuit.

Describin the various parts by reference numerals 1 lndicates a suitable box or case which serves to house the various parts of the apparatus. The top of the case is provided with' a circular hole 2 into which to set the band 3, and integrally connected to this band is the cover 4. A small spring catch 5 is mounted on the cover to hold it in closed osition when desirable. In alignmentwitli said hole and attached to the other side of the case is the insulating member 6, which can be made of any suitable material as bakelite, formica or mica. The lower end istapered as at 7 and provided with the hollow heating coil cores 8 and a tubular member 9 projects upwardly inside and is preferably formed integral therewith. This tubular member is flared at the upper end as at 10 to surround the underside of the internal electrode 11. The passageway through this member connects to the passageways of each of the heating coil cores 8. The internal electrode 11 is formed with a stem 12 which is threaded into the lower end of the insulating member and provided with a binding post 13. At its upper end it is formed with a cavity 15 for the reception of a crucible 16 which preferably is of non-corrosive material as porcelain or glass and is readily removed for cleaning or other purposes. The electrode is also provided with a series of small openings or holes 17 adjacent its upper ede and a cover 18, the

urposes of which w1ll be explained later.

he external electrode consists of a metallic` band 19 fastened to the outer walls of the insulating member at a suitable hei ht so as to be opposite the internal electro e.

The U-tube assembly comprises a supporting plate 22 and attached thereto on the underside are the U-tube supports 23-24. The support 23 is provided with a vertical bore 30, the lower end of which receives one leg of a U-tube 25, and the other end is closed by a threaded plug 26. A horizontal tapered bore 27 intersects the vertical bore 30 and is adapted to receive a hollow tapered plug connector 2S which is attached to a hose member 29. The support 24 is provided with a vertical bore 31 and an intersecting horizontal bore 32, the bore 31 receiving at its lower end the other leg of the U-tube and at its upper end a threaded plug 33. The top of the case is slotted as indicated at 35 to permit the U-tube assembly to be seated therein in such way as to allow the horizontal bore 32 to be in alignment with the bore 36 of the insulating member 6. A suitable catch as indicated at 37 serves to lock the assembly in the box. The U-tube may be readily cleaned or the liquid therein renewed by unlocking the catch 37 and removing the U-tube assembly. The plugs 26 and 33 are then removed and the tube 25 is readily cleaned by a suitable brush or cleaner.

The end of the case adjacent the heating coil is provided with a series of openings 40 which are fitted with bushing members 41 and permit air to bedrawn into the case and up t rough the heating coils.

Any suitable apparatus and circuit may be provided for the production of the brush discharge between the electrodes 11 and 19, and as an illustration of such I have shown a primary coil 45 fitted with a vibrator or i current interrupter 46 and connected in series with the primary of a Tesla coil 47. The secondary of the Tesla coil is connected to the discharge gap. A condenser 48 is shunted across the vibrator to prevent excessive sparking, and a suitable switch 49 is mounted on the exterior of the case to open and close the circuit. The heating coils are connected in series and shunted across the line which is brought through the insulating bushmg member 50, in one end of the case. The winding for the coils may have a resistance suitable for direct connection to 110 volts A. C. or D. C. line` or may have a lower resistance permitting use of the instrument on battery circuits.

In using the instrument for collective treatment, the cover 4 is opened and a suitable oil is placed in the cup 16 and the cover 18 is placed over the cup.. rlhe vibrator is now adjusted to give the proper discharge across the gap and the coils 8 heat the air and cause a flow of dry heated air up through the member 9 which serves to vaporize the oil in the cup and drive the vapor out through the openings 17 where it is mixed with lthe ozone produced by the discharged gap and this mixture is then expelled into the room through the opening 2 in the case box.

For individual treatment the cover 4 is closed and the mixture of ozone and vapor.

ized eil is drawn through the U-tube which may contain any liquid or oil desired. y The oil may be omitted from the cup 16 and U- tube 25, and ozone alone used, or an oil may be used which absorbs any impurities such as any of the oxides of nitrogen which may be formed with the ozone, and thereby produce pure ozone. 1t will readily be seen that the instrument is adapted for a number of dierent treatments and uses and the various parts containing oils or other liquids mag be easily cleaned.

aving thus described my invention, what I claim is 1. An apparatus of the class described comprising a plurality of electrodes adapted to receive an electrical discharge therebetween, one of said electrodes being provided with a recessed portion to receive a liquid, an insulating member interposed between said electrodes, and means for heating and conducting air to said liquid.

rneaoaa 2. An apparatus of the class described comprising an internal and an external electrode adapted to receive an electricall disv a tubular member surrounding said internaly electrode for conducting heated air thereto and an insulating member interposed between said electrodes and formed integral with said tubular member.

3. An apparatus of the class described comprising a case, an insulating member supported is said case and provided for the plurality of electrodes adapted to receive an electrical discharge therebetween, means for supporting a liquid adjacent said electrodes a relatively large opening in said case for emitting the products oi said discharge and the vapors of said liquid to the room, means for closing said opening, and means for delivering the products of said discharge through a smaller opening for individual use.

4. rAn apparatus of the class described comprising a plurality of electrodes, adapted to receivean electrical discharge therebetween, an insulating member interposed between said electrodes, and means for vaporizing a liquid and mixing said vapor with the products of the discharge.

5. An apparatus of the class described comprising a hollow insulating member provided with an internal and an external electrode adapted to receive an electrical discharge therebetween, a tubular member surrounding said internal electrode, a plurality of heating coils for heating and conducting air to said tubular member and means for supporting a liquid to be vaporized between said tubular member and said electrodes.

6. An apparatus of the class described comprising a plurality of electrodes adapted to receive an electrical discharge therebetween, means for heating and conducting air tosaid electrodes, and means for supporting a liquid adjacent said electrodes thereby to volatilize said liquid and admix the vapors thereof with the products of said electrical discharge.

In testimonywhereof, I hereunto affix' my signature.
